SRAM cassettes/Dura Ace freehub bodies

I know that the original Dura Ace 10 speed hubs were good with only 10 speed, and I think I have that version hub on a set of wheels. Will SRAM 10 speed cassettes work with those hubs?

Thanks,

Tom

OK, a little research before I asked the question would have been good...I found the answer from Sheldon Brown, and the 7800 hub bodies used taller splines; only compatable with Shimano Cassettes. They reverted to the old splines for the 7850 series and beyond hubs.

So, new question. Are the hub bodies interchangeable between the two hubs? I can call Shimano tech, but figured I'd start here...

Nope. Entirely different hub design.

^+1. I have actually confirmed from Shimano North America that those freehub bodies are not interchangeable.

It's obvious from the exploded diagrams themslves for FH-7800/FH-7850 that they are not compatible. The latter is standard shimano style freehub while the former has exposed pawls/springs.
